The Senate Foreign Relations Committee is hearing testimony Tuesday about the potential use of military force in Syria. Testifying are Secretary of State John Kerry, Defense Secretary Chuck Hagel and Joint Chiefs of Staff Chairman Gen. Martin Dempsey.

The hearing will be closely watched around the world as lawmakers weigh whether or not to formally authorize the use of U.S. forces in response to the alleged use of chemical weapons on Syrian refugees. As of now, Congress remains skeptical.

The hearing begins at 2:30 p.m. eastern time.
